STRUCT DRM_IVPU_BO_INFO(9)

💅 struct drm_ivpu_bo_info(9) — like, the Kernel API Manual page, bestie 🎀

okay so first things first: this is a page straight outta the Kernel API Manual, and it's all about struct drm_ivpu_bo_info — yes, that's the whole vibe. It's the "Query buffer object info" struct, and honestly? She's giving lookup-table energy and I'm obsessed. ✨

🌸 NAME 🌸

struct drm_ivpu_bo_info — Query buffer object info 🫶

Like, you hand it a BO and it tells you stuff about it. That's the whole job. Iconic, honestly, no notes.

---

✨ SYNOPSIS ✨

struct drm_ivpu_bo_info {
    __u32 handle;
    __u32 flags;
    __u64 vpu_addr;
    __u64 mmap_offset;
    __u64 size;
 };

look at her. five fields. perfectly balanced. the way that __u32 and __u64 just coexist... 💅

🦋 Members 🦋

okay so let's go through the whole cast, one by one, main character by main character:

• handle — Handle of the queried BO 👑 — literally the ID of the buffer object you're asking about, iykyk.
• flags — Returned flags used to create the BO 🎀 — they come back to you from creation time, like a little receipt.
• vpu_addr — Returned VPU virtual address ⭐ — the VPU's virtual address, returned to you, no cap.
• mmap_offset — Returned offset to be used in mmap. 0 in case the BO is not mappable. 🌈 — yes bestie, that 0 means not mappable, don't come for me, that's just what it says.
• size — Returned GEM object size, aligned to PAGE_SIZE 💖 — and it's aligned to PAGE_SIZE, so it's tidy. slay.

fr fr, mmap_offset being 0 is the "not mappable" signal — so if you see a 0 there, that's your answer, don't @ me. 💀
